Hi
Since no one reads this bit of the OP, let's get to it. Credit to Cloudxddd for posting the sd card fix in another thread.

Enable ADB shell
On your Tablet:
  1. Open the settings app
  2. Scroll down to 'About tablet'
  3. Select 'Software information'
  4. Continuously tap on 'Build number' over and over until at the bottom of the screen you see a toast saying "Developer mode has been enabled"
  5. Go back to the main settings page and scroll down, select the new 'Developer options' button
  6. Enable 'USB debugging' (press OK to confirm)
On Ubuntu:
  1. Install ADB: sudo apt install adb
  2. Plug your tablet into your PC via USB
  3. Start ADB and check your device is connected: adb devices (if more than one device is listed, unplug your second android phone/tablet
  4. You may need to approve the connection on your tablet
  5. Run ADB shell: adb shell

Remove stock apps (bloatware)
In ADB shell (see above):
  1. List the apps installed: pm list packages
  2. Removing some apps will cause your tablet to brick (fixed by doing a factory reset from the recovery menu), so be careful
  3. Search APK Mirror for the package name if you don't know what app you're looking at
  4. To uninstall an app from your user but keep it on the device: pm uninstall -k --user 0 <packagename>
  5. Reboot the device to ensure it can boot successfully: reboot
  6. Reply below with the apps you removed and whether it was successful / safe
  7. Reinstall that app: cmd package install-existing <package name> (or do a factory reset if it failed)
  8. Completely remove the app and reclaim the space if you're certain it can be removed safely: pm uninstall <packagename>
  9. Reboot the device to ensure it can boot successfully: reboot
Note: Some apps reinstall when you reboot.

Yep, same. I split the card 50/50. After a reboot, the actual card even showed as only half the size. But there was just no button at all in any app´s storage settings. And I know what to look for! Because my thine actually has that exact button. To me this looks like Samsung just flat out disabled the feature.

I just hope someone comes up with an answer to samsungs mess up as the tablet is good . Would rooting the tablet make it so I could save apps to the sd card .

I did this on my Windows laptop. ADB wouldn't recognize the tablet until I downloaded the drivers from Samsung and installed them. I hadn't had to install anything other than the Google drivers until now.

Oh rite could you possibly post a link to the drivers please. When I open ADB it shows the serial number of my table so I just thought all was OK but maybe installing the official drivers from samsung will solve this issue . Thanks mate .

Brilliant! I almost quit initially but then realized you spelled partition wrong.

  1. List disks: sm list-disks
  2. Partition the disk to be used entirely for apps to SD: sm parition <DISK> private
  3. Partition a percentage of the disk to be used for apps to SD: sm partition <DISK> mixed <number>

But after that it still didn’t work. But I heard Rona cheering me on. Dug into the crates of Google and found this and it worked! I used AppMgr III to move the apps. I was able to move Amazon successfully.

I followed these steps, and everything seems to work. Only some apps can be moved to the SD card, but that's not surprising.

However, after rebooting, Android decides that the app data is corrupted, and forces me into safe mode, from which a factory reset is the only solution.

So this only works for me if I never reset or power off the device.

Have to say, I'm never buying Samsung again. I've just had so many issues with this device. Even trivial stuff, like not being able to connect to Wifi via WPS when setting up the device (or when doing a factory reset)

After rebooting, I the tablet doesn't restart - it boots into Android Recovery, and the rescue summary shows I get NullPointerException: Attempt to invoke virtual method WindowManagerService.detectSafeMode() on a null object reference.

according to me, this method doesn't seem to work. i've got a 64gb microsd, followed the steps as indicated, after reboot the sd card shows up as "corrupted" and everytime a format is needed. unfortunately, moving apps to sd seems to be not possible. such a shame since the tab s7 can do it and this one not. hope that with android 11 update (if ever there will be) they enable this feature.

for me it works !

did you understand how adoptable storage works ??? no, then read this!
android.stackexchange.com

'adoptable-storage' tag wiki

Q&A for enthusiasts and power users of the Android operating system
android.stackexchange.com android.stackexchange.com


i did the following and it works for me:

1. format your inserted SD-Card in the Tab A7 and dismount the SD-card after formatting
2. enable USB-debugging and connect with adb console to Tab A7
3. enter the following commands

Code: 
adb shell
sm list-disks adoptable

i got the result
Code: 
disk:179,32

my SD-card is 128GB size and i want 32GB (25% of total SD-Card)
for use as internal adopted storage

therefore i want 96GB (75% of total SD-Card) as external SD-card

to do this use the following commands (as adviced in posting #12)

Code: 
sm set-force-adoptable true
sm partition disk:179,32 mixed 75
sm set-force-adoptable false


then i rebooted my Tab A7 and mounted the external SD-card (which shows 86,9GB)

the internal storage shows two items
1. internal storage 32GB
2. SD-Card adopted storage ( it doesnt tell you the adopted storage size but
it says 100GB used out of 128GB) which means 28GB are free for further usage,
at this point i have moved already all apps which are moveable to external storage.

i use the app "AppMgr III" as App 2 sd - utility

there are no errors or other problems after rebooting or during normal use.
it just works

thx, found out that the sd card was not working correctly. tried with another one and worked flawlessly!
update: the method seems to be very unstable, if compared to app installed on internal memory. anytime i try to run an app, it's ok for 10-15 minutes, then suddenly blocks and reboots. this happens everytime and once rebooted, it will show that apps are not installed on ext sdcard; temporary fix when rebooted again, but it's very bothering.

FYI those methods work but are limited as you can't move certain apps or can't move their data sometimes.

If you're looking for even more space, I'd recommend App2sd (by Vicky Bonick, NOT the appMgr iii automatisation thing). You'll have to format your sd card with two partitions :
- one FAT32, that will be used as a "standard" sd card, visible by the device and all
- one F2FS, that will be used to link apps to sd card and will be invisible to most of the apps.
when asked to provide su.dpost-fs-data.d/service.d adress I used :
Code: 
/data/adb/service.d

But, yes it requires root access. I'm still giving it a try but so far this is the only method that I've managed to move stuff like Genshin impact and its 8GB of data that somewhat disappear into thin air using other methods.

EDIT : after messing around for a few hours. This method is still not perfect ... I have troubles moving some obb files with it. But it's still worth a shot

Thanks, followed your guide and initially it worked correctly.
I also rebooted the table and it still worked.
However now (after a shutdown) the SD card is recognized as corrupt / damaged (translated).
It is still part of the adoptable storage.

I earlier reported it didn't work anymore after a reboot.
However checking a few days later it works again.
I guess it ran out of battery and rebooted.....
Thanks.

It works great on my SM-T500. I was able to use my 64GB SD Card as Device Storage. I was able to move Asphalt 8 game from Internal Storage to SD Card

    1. Open the settings app
    2. Scroll down to 'About tablet'

    On Ubuntu:
    1. Install ADB: sudo apt install adb
    2. Plug your tablet into your PC via USB
    3. Start ADB and check your device is connected: adb devices (if more than one device is listed, unplug your second android phone/tablet
    4. You may need to approve the connection on your tablet
    5. Run ADB shell: adb shell

    Remove stock apps (bloatware)
    In ADB shell (see above):
    1. List the apps installed: pm list packages
    2. Removing some apps will cause your tablet to brick (fixed by doing a factory reset from the recovery menu), so be careful
    3. Search APK Mirror for the package name if you don't know what app you're looking at
    4. To uninstall an app from your user but keep it on the device: pm uninstall -k --user 0 <packagename>
    5. Reboot the device to ensure it can boot successfully: reboot
    6. Reply below with the apps you removed and whether it was successful / safe
    7. Reinstall that app: cmd package install-existing <package name> (or do a factory reset if it failed)
    8. Completely remove the app and reclaim the space if you're certain it can be removed safely: pm uninstall <packagename>

    Hi
    Since no one reads this bit of the OP, let's get to it. Credit to Cloudxddd for posting the sd card fix in another thread.

    Enable ADB shell
    On your Tablet:
    1. Open the settings app
    2. Scroll down to 'About tablet'
    3. Select 'Software information'
    4. Continuously tap on 'Build number' over and over until at the bottom of the screen you see a toast saying "Developer mode has been enabled"
    5. Go back to the main settings page and scroll down, select the new 'Developer options' button
    6. Enable 'USB debugging' (press OK to confirm)
    On Ubuntu:
    1. Install ADB: sudo apt install adb
    2. Plug your tablet into your PC via USB
    3. Start ADB and check your device is connected: adb devices (if more than one device is listed, unplug your second android phone/tablet
    4. You may need to approve the connection on your tablet
    5. Run ADB shell: adb shell

    Remove stock apps (bloatware)
    In ADB shell (see above):
    1. List the apps installed: pm list packages
    2. Removing some apps will cause your tablet to brick (fixed by doing a factory reset from the recovery menu), so be careful
    3. Search APK Mirror for the package name if you don't know what app you're looking at
    4. To uninstall an app from your user but keep it on the device: pm uninstall -k --user 0 <packagename>
    5. Reboot the device to ensure it can boot successfully: reboot
    6. Reply below with the apps you removed and whether it was successful / safe
    7. Reinstall that app: cmd package install-existing <package name> (or do a factory reset if it failed)
    8. Completely remove the app and reclaim the space if you're certain it can be removed safely: pm uninstall <packagename>
    9. Reboot the device to ensure it can boot successfully: reboot
    Note: Some apps reinstall when you reboot.

    Apps that might be safe to remove - Please reply with updates

    Brilliant! I almost quit initially but then realized you spelled partition wrong.

    1. List disks: sm list-disks
    2. Partition the disk to be used entirely for apps to SD: sm parition <DISK> private
    3. Partition a percentage of the disk to be used for apps to SD: sm partition <DISK> mixed <number>

    But after that it still didn’t work. But I heard Rona cheering me on. Dug into the crates of Google and found this and it worked! I used AppMgr III to move the apps. I was able to move Amazon successfully.

    according to me, this method doesn't seem to work. i've got a 64gb microsd, followed the steps as indicated, after reboot the sd card shows up as "corrupted" and everytime a format is needed. unfortunately, moving apps to sd seems to be not possible. such a shame since the tab s7 can do it and this one not. hope that with android 11 update (if ever there will be) they enable this feature.

    for me it works !

    did you understand how adoptable storage works ??? no, then read this!

    'adoptable-storage' tag wiki

    Q&A for enthusiasts and power users of the...
    android.stackexchange.com android.stackexchange.com


    i did the following and it works for me:

    1. format your inserted SD-Card in the Tab A7 and dismount the SD-card after formatting
    2. enable USB-debugging and connect with adb console to Tab A7
    3. enter the following commands

    Code: 
    adb shell
sm list-disks adoptable

    i got the result
    Code: 
    disk:179,32

    my SD-card is 128GB size and i want 32GB (25% of total SD-Card)
    for use as internal adopted storage

    therefore i want 96GB (75% of total SD-Card) as external SD-card

    to do this use the following commands (as adviced in posting #12)

    Code: 
    sm set-force-adoptable true
sm partition disk:179,32 mixed 75
sm set-force-adoptable false


    then i rebooted my Tab A7 and mounted the external SD-card (which shows 86,9GB)

    the internal storage shows two items
    1. internal storage 32GB
    2. SD-Card adopted storage ( it doesnt tell you the adopted storage size but
    it says 100GB used out of 128GB) which means 28GB are free for further usage,
    at this point i have moved already all apps which are moveable to external storage.

    i use the app "AppMgr III" as App 2 sd - utility

    there are no errors or other problems after rebooting or during normal use.
    it just works

    Oh rite could you possibly post a link to the drivers please. When I open ADB it shows the serial number of my table so I just thought all was OK but maybe installing the official drivers from samsung will solve this issue . Thanks mate .

    Here is the link for the Samsung USB drivers: https://developer.samsung.com/mobile/android-usb-driver.html

    Without the drivers, ADB does not show the device at all, so I think you're fine.
